Questions about sheep's wool or natural loft insulation in Gwynedd
Which council covers my address in Gwynedd?
Councils in Gwynedd include Gwynedd and Isle of Anglesey. Your council matters for building control questions and some funding schemes.
Are your prices the same across Gwynedd?
Yes. Our guide prices are the same everywhere we work, and they include normal travel. Your fixed price depends on your loft, not your postcode.
Is sheep's wool insulation worth the extra cost?
In an older breathable house, or if you care about the material, often yes. In a modern semi with plasterboard ceilings the extra cost buys little performance.

Insulation-grade sheep's wool is treated against insects. We use products sold for loft insulation, not raw fleece.
